[. . . ] See page 9. 2 Low-drive, long-track, eight roller undercarriage provides outstanding grading ability and stability. K-Bogie undercarriage system improves traction, component durability, and operator comfort. See page 8. Extra-low machine profile provides excellent machine balance and low center of gravity. Track shoe slip control system (optional) reduces operator fatigue. See page 7. 3 D375A-6 C R AW L E R D O Z E R CRAWLER DOZER D375A-6 CONTROL FEATURES Komatsu's new ergonomically designed control system "PCCS" creates an operating . environment with "complete operator control" Power Train Electronic Control System Smooth operation D375A-6 uses a newly designed power train electronic control system. [. . . ] In addition, countermeasures are indicated in 4 stage codes to ensure safety and prevent the machine from major problems. Replacement times for oil and filters are also indicated. Photo may include optional equipment. Centralized service station To ensure convenient maintenance, the transmission and torque converter oil filters are both arranged next to the power train oil level gauge. Oil pressure checking ports Pressure checking ports for power train components are centralized to promote quick and simple diagnosis. Enlarged engine room Maintenance warning screen Engine room space is enlarged by increasing engine hood height, facilitating maintenance of the engine and related equipment. Solid engine hood prevents dust and rain from entering and keeps the engine clean. Hexagonal pressurized cab The cab's new hexagonal design and large tinted glass windows provide excellent front, side and rear visibility. Air filters and a higher internal air pressure combine to prevent dust from entering the cab. Comfortable ride with new cab damper mounting and K-Bogie undercarriage D375A-6's cab mount uses a new cab damper mounting which further improves viscous damper and provides excellent shock and vibration absorption capacity with its long stroke. The cab damper mounting, combined with new K-bogie undercarriage, softens shocks and vibrations while traveling over adverse condition that are impossible to absorb with conventional cab mounting methods. The soft spring cab damper isolates the cab from machine body, suppressing vibrations and providing a quiet, comfortable operating environment. Gull-wing engine side covers Gull-wing engine side covers facilitate engine maintenance and filter replacement. Side covers are a thick two-piece structure with bolt-on latch to improve durability and repairability. Fresh air intake from rear of engine hood The air conditioner air intake port is now located at the rear of the engine hood where there is minimal dust. Cleaning interval of the filter is greatly extended, and use of a new structure filter element facilitates cleaning and replacement. Abnormality warning screen Maintenance List screen for replacement time display Cab damper mounting Rubber Boot Large multi-lingual LCD color monitor A large user-friendly color monitor enables safe, accurate and smooth work. Improved screen visibility is achieved by use of TFT (Thin Film Transistor) liquid crystal display that can easily be read at various angles and lighting conditions. Display data in 10 languages to globally support operators around the world. Rubber Low Maintenance Costs Track link with wedge ring New D375A-6 track links feature Pin press fitting force + reduced press-fit force and a wedge ring holding force wedge ring. Conventional track pins are retained only with a large press-fit force. The new track link divides pin forces between the Track guiding wedge ring and press-fit force. This guard results in easier service with Wedge ring reduced pin damage when turning pins and bushings. The result is improved undercarriage life and reduced maintenance cost through reduced wear, greater pin reusability, and reduced maintenance man-hours. increase mechanical strength, provide longer life, and protect the system from damage. Silicon Oil Flat face O-ring seals Flat face O-ring seals are used to securely seal all hydraulic hose connections and to prevent oil leakage. Spring New suspension seat D375A-6 uses a new suspension seat. Fore and aft sliding rails and suspension spring increases strength and rigidity and reduces play of joints. Fore Enclosed hydraulic piping Hydraulic piping for the blade tilt cylinder is completely housed in the push arm protecting it from damage. Modular power train design Power train components are sealed in a modular design that allows the components to be dismounted and mounted without oil spillage, making servicing work clean, smooth, and easy. Indicators and aft sliding amount is designed to fit all operators. In addition, air suspension seat with seat isolator is optionally available, that reduces vertical and lateral vibrations more Function switches effectively. Highly reliable electric circuit The electrical circuit reliability is increased by utilizing dust, vibration and corrosion resistant "DT connectors". The reinforced electrical wiring harnesses include a circuit breaker and are covered with a heat-resistant material to Basic operation switches Maintenance-free disc brakes Wet disc brakes require less maintenance.
